 * 检查 mp-harmony 项目的子包 HAR 配置在 4 个地方是否同步:
 *   1. mp-harmony/build-profile.json5 的 modules 数组
 *   2. entry/oh-package.json5 的 dependencies
 *   3. entry/har-deps-required.json5 的 requiredHarDeps (单一事实源)
 *   4. ascf_build 实际目录
 *
 * 任何一处不一致 → 立即报错并指出哪一处需要修改。
 * 防止新增/删除子包时漏改某处导致 build/runtime 故障。
 *
 * 使用:
 *   node scripts/check-subpackage-sync.js
 *   node scripts/check-subpackage-sync.js --strict  # 不一致即 exit 1 (CI 用)
 *
 * 输出:
 *   ✓ 5 个子包配置完全一致
 *   或
 *   ✘ 缺失 [pages_extra] 在以下位置:
 *     - build-profile.json5 (mp-harmony)
 *     - entry/oh-package.json5
 *     建议操作: ...
